COTTON-PICKER.

Be it known that I, HARRISON T. NoBLE, a citizen of the United States,residing at kTogo, in the co-unty of Major, State of Oklahoma, haveinvented certain new and useful Improvements' in Cotton-Pickers; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to cotton pickers, and has for an object toimprove that class of cotton pickers described in U. S. Letters Patentissued to me on the 25th day Vof January, 1910, No. 947 ,559, by theprovision of a novel pneumatic-conveyer and cotton receptacle.

With the above object in View, the invention consists of certain noveldetails of construction and combination of parts hereinafter fullydescribed and claimed, it being understood that various modications maybe made in the minor details of construction within the scope of theappended claim.

In the accompanying drawings forming part of this specifica-tion, Figure1 is a plan view of the device. Fig. 2 is a side elevation of thedevice. Fig. 3 is a side elevation of the reverse side from that shownin Fig. 2. Fig. 4 is a rear elevation of the device. Fig. 5 is alongitudinal sectional view taken on the line 5-5 Fig. 1. Fig. 6 is across sectional View taken on the line 6-6 Fig. 2.

Referring now to the drawings, in which like characters of referencedesignate similar parts, 10 designates a wheeled wagon, upon the forwardend of which is supported a gas engine 11 or other motor. Upon the rearend of the wagon is supported a box 12, which is provided with a hingeddoor 13 on the rear side. Supported upon posts 13 carried by the wagonin advance of the box is a fan casing 14, having a centrally disposedsuction opening 15 in one side which communicates directly with an airtight casing 16 secured to the side of the fan casing, the air tightcasing opening into the box 12.

An intake conduit 17 is support-ed in horizontal posit-ion transverselyacross the rear upper corner of the box, and communicates through anopening 18 with the box. At intervals throughout the longitudinal extentof the conduit and in communication Specification of Letters Patent.

Application filed August 30, 1912. Serial N o. 717,907.

therewith, are a plurality of suction tubes 18, each having mountedat/its free end a picker nozzle 18 formed with a flared open mouth. Ineach pickerv nozzle is a lever actuated spring controlled cut off valve19, which is adapted to regulate the supply of cotton gathered throughsaid suction tube and conveyed through said conduit and communicatingbox and air tight casing to said fan casing. Working in said :tan casingis a suction fan 20 which is mounted upon a shaft 21 that is journaledin bearings 22 carried on the outer sides of the tan casing and airtight casing. A driving pulley 22 is fixed to the shaft and over thisdriving pulley and the engine pulley 23 a belt 24 is trained andactuates the fan.

The fan casing is provided at the top with an outlet opening 25. Apneumatic conveyer conduit 26 is fixed to one side of the fan casing andextends above and below the fan casing, the conduit inclining rearwardlyand downwardly along one side of the box 12, and o ening at the lowerend into a conduit 2 which extends transversely across the bottom of thebox, and which in turn opens into a forwardly and upwardly inclinedconduit 27 that extends longitudinally of the wagon and communicates atthe end with a cotton receptacle 28, which is closed by a hinged cover29. The conduit 26 isprovided With an opening 30 which registers withthe fan casing discharge opening 25, and the upper end of the conduit 25is closed by a` hinged door 31.

In operation, suppose that the pneumatic conveyer door is closed. Thecotton which is drawn into the fan casing by the suction of the Jfan isejected through the discharge opening of the fan casing into thepneumatic conveyer and is thence conveyed through the conveyer by theblast from the fan into the cotton receptacle 28. Upon the receptacleand pneumatic conveyer being filled with the cotton, the vblast from thefan will blow the door 31 of the pneumatic conveyer open with aresultant ejection of the cotton through the upper end of the conveyer,thus giving visible evidence that the cotton receptacle and conveyer ischoked with the accumulated cotton.

The door 31 is provided at the rear hinged edge with a counter-balancingweight 32 which serves to maintain the door in open position when open,and for closing the door, a cable 33 is attached to the free edge of thedoor and trained through a guide eye 34 carried on the edge of the upperend of the conduit, as shown, the cable being thence carriedforwardlylalong the outer side of the air tight casing 16 and trainedthrough a guide eye 35 carried on one of the posts which support the fancasing, the cable being terminally equipped with a grip 36 by means ofWhich the cable may be pulled to open the door.

The hinged door 13 of the box 12 is normally held closed by a bowedspring 37, and may be rocked open against the tension of this spring tofacilitate access to the interior of the box for the removal of any,

cotton which may accumulate therein.

What is claimed is In a cotton picking machine, a durigable support, abox thereon, a fan casing on said support, an air-tight casing on oneside of said fan casing communicating With said box` and communicatingwith a centrally disposed intake opening on said fan casing, a conduitmounted to extend horizontally across said box and communicatingtherewith, a plurality of suction tubes carried by and communicatingwith said conduit, a receptacle on said support, a pneumatic conduitcommunicating With said fan and With said receptacle, said conduitextending above said fan and having an open upper end, and acounter-balanced door normally closing said open upper end.

In testimony whereof, I aliix my signature, in presence of tWoWitnesses.
